NatGateway nat-xxx is in state failed and hence failed to stabilize Detailed failure message: Network vpc-xxx has no Internet gateway attached

A public NAT has to be deployed in VPC or subnet with a public route table

If you deploy a NAT and get this error:

Resource handler returned message: “Error occurred during operation ‘NatGateway nat-xxx is in state failed and hence failed to stabilize. Detailed failure message: Network vpc-xxx has no Internet gateway attached’.” (RequestToken: xxx, HandlerErrorCode: GeneralServiceException)

That means you’ve likely tried to deploy a public NAT into a private VPC.

I explain public and private VPCs and Subnets here.

Public and Private VPCs and Subnets (Route Tables)

ACM.61 Adding custom route tables with names to our AWS VPCs

medium.com

Create a public subnet with and Internet Gateway in the Route table for a NAT. Don’t add a route table for the subnets you want to be private but add a route to the NAT Gateway to access the Internet.

About to publish some code to show how to do that and have related posts here in my posts on Network Security:
